Sometimes when removing screws, we use the wrong size screwdriver or try to remove them too quickly without enough pressure applied. When this happens, we start stripping the slotted head of the screw, creating a very loose and sloppy fit.
THE MOMENT YOU THINK YOU HAVE BEGUN TO STRIP THE SCREW HEAD,
STOP TRYING TO REMOVE IT TO PREVENT FURTHER DAMAGE!
To solve this problem, put a wide rubber band between the head of the screw and the screwdriver. I recommend using a screwdriver that is one size larger to help achieve more contact. The rubber band should fill in the stripped area and provide enough grip to help turn the screw. This works best if you apply heavy pressure at a slower turning speed. This should do the trick if the head hasn’t been stripped too badly. Problem solved with the help of a simple rubber band.
